Accepted name: atrolysin A
Reaction: Cleavage of Asn3┼Gln, His5┼Leu, His10┼Leu, Ala14┼Leu and Tyr16┼Leu in insulin B chain; removes C-terminal Leu from small peptides
Other name(s): Crotalus atrox metalloendopeptidase a; hemorrhagic toxin a; Crotalus atrox α-proteinase; Crotalus atrox proteinase; bothropasin
Comments: A hemorrhagic endopeptidase of 68 kDa, one of six hemorrhagic toxins in the venom of western diamondback rattlesnake. The 60 kDa hemorrhagic toxin 1 of Crotalus ruber ruber shows identical specificity [2]. In peptidase family M12 (astacin family). Related metalloendopeptidases from rattlesnake venoms are EC (atrolysin B), EC (atrolysin C), EC (atroxase), EC (atrolysin E), EC (atrolysin F), EC (adamalysin), EC (horrilysin), and EC (ruberlysin)
